Background: Metered dose inhalers (MDIs) are important devices for delivering inhaled medications; however, they have an outsized carbon footprint due to their propellant gas. Many short-acting beta-agonist inhalers contain HFA-134a which has a global warming potential >1000 fold higher than carbon dioxide. We aimed to determine the practices around MDI use and disposal within Australia's major lung function testing laboratories and identify the actions that most influence the carbon footprint of bronchodilator responsiveness (BDR) testing.

For the Herpes simplex virus 1 (HSV-1), latent infection of neurons is characterized by association with repressive heterochromatin marked with Polycomb silencing-associated lysine 27 methylation on histone H3 (H3K27me). However, whether H3K27 methylation plays a role in repressing lytic gene expression in non-neuronal cells is unclear.
